10 Causes of Swollen Feet
Cause #7: Lymphedema
Lymphedema occurs when the lymphatic fluid in the lymph vessels collect in the tissues. Lymphatic fluid is rich in protein. It can occur in infections such as filariasis or when the lymph nodes are removed as part of the treatment for cancer. Lymph nodes are part of the immune system that help filter the lymphatic fluid and destroy trapped pathogens such as bacteria.
Any issues with the lymphatic vessels or lymph nodes that causes blocked movement can cause swelling in the affected area such as the feet. Left untreated, it can cause impaired wound healing and infection. Other symptoms of lymphedema include a sensation of heaviness, limited motion, repeated infection, thickening of the skin, and aches. Management includes light exercise that encourage the drainage of lymphatic fluid, compression bandages, massage, and surgery in severe cases.
